Abstract

The invention discloses a sand mixer and belongs to the technical field of machine casting. The sand mixer comprises a frame, a sand mixing barrel, a motor and a spindle. The sand mixing barrel is arranged on the frame; the motor is arranged at the center of a top cover of the sand mixing barrel; the spindle is connected with the motor; the spindle is passed through the top of the sand mixing barrel into the same; the sand mixing barrel includes an upper mixing tier, a rolling tier and a lower mixing tier arranged sequentially from top to bottom. The sand mixer herein has the advantages that the upper mixing tier, the rolling tier and the lower mixing tier help inject raw sand, water and auxiliaries simultaneously into the sand mixer and mix them well, pipeline operation is finished in thesand mixer, the whole process ensures that all the materials can pass through the upper mixing tier, the rolling tier and the lower mixing tier in sequence, the materials in the sand mixing barrel can be mixed well, the problem that materials above and below cannot be fully circulated and mixed is solved, and grinding helps avoid the caking problem.

Description

technical field [0001] The invention belongs to the technical field of mechanical casting, and in particular relates to a sand mixer. Background technique [0002] The sand mold is a casting cavity made of raw sand, water and other auxiliary materials during the casting process. Whether the proportioning and mixing of materials are uniform is the decisive factor for the quality of the sand mold, and the sand mixer is a machine used to mix the above materials evenly, so that the surface of the sand particles is evenly coated with auxiliary materials to become the molding sand for the preparation of sand molds. The molding sand should be loose without agglomeration. According to the characteristics of the sand mixing process, the sand mixer can be roughly divided into four types: the roller sand mixer, which mainly uses rolling and rubbing; the blade sand mixer, which mainly mixes the action; the rotor sand mixer , both rubbing and mixing functions; roller sand mixer, both r...
